Free gold recovery by coal-oil agglomeration
The gold mining industry has mainly relied upon the use of highly polluting chemicals such as mercury and cyanide to recover gold from its ores. The Coal Gold Agglomeration (CGA) process was developed some years ago and has the advantage in that gold is recovered by a procedure which has little or no negative impact on the environment. A gold ore containing liberated gold particles is
